This experiment was conducted during autumn growing season of 2016-2017 under unheated greenhouse environment at the field station college Agriculture-University Tikrit to study effect seaweed, and organic extracts spraying on growth yield tomato's (Lycopersicon esculentum Mill) three hybrids. The following nutrients were used; Alga600, Seaweed, Max in addition control treatment. hybrids were; ...

Citrus is the first tree crop in terms of fruit production. The colour of Citrus fruit is one of the main quality attributes, caused by the accumulation of carotenoids and their derivative C30 apocarotenoids, mainly β-citraurin (3-hydroxy-β-apo-8'-carotenal), which provide an attractive orange-reddish tint to the peel of oranges and Mandarins. Though carotenoid biosynthesis and its regulation h...

There is now biochemical and genetic evidence that oxidative cleavage of cis-epoxycarotenoids by 9-cis-epoxycarotenoid dioxygenase (NCED) is the critical step in the regulation of abscisic acid (ABA) synthesis in higher plants. The peel of Citrus fruit accumulates large amounts of ABA during maturation. To understand the regulation of ABA biosynthesis in Citrus, two full-length cDNAs (CsNCED1 a...

The color of tomato fruit is mainly determined by carotenoids and flavonoids. Phenotypic analysis of an introgression line (IL) population derived from a cross between Solanum lycopersicum 'Moneyberg' and the wild species Solanum chmielewskii revealed three ILs with a pink fruit color. These lines had a homozygous S. chmielewskii introgression on the short arm of chromosome 1, consistent with t...

doi:10.1111/j.1399-3054.2006.00642.x This research compares effects of the compound 5-chloro-3-methyl-4-nitro1H-pyrazole (CMNP), a plant growth regulator that selectively promotes abscission in mature citrus fruit (Citrus sinensis), and the ethylene-releasing agent ethephon (2-chloroethylphosphonic acid). Application of CMNP and ethephon to mature citrus fruit reduced fruit detachment force and...

the effects of uv-c illumination at the dosage of 6.6 kj m-2 on postharvest quality of mango fruit cv. ‘kaew kamin’ during storage at 25 or 12°c were investigated. the changes in fresh weight, texture, ripening index (ri), peel and pulp colours, visual appearance, total carotenoids (tc) and ascorbic acid (asa) content were determined on days 0, 4, 8, 12 and 16 of storage. uv-c irradiation effec...

Carotenoids in the peel of harvested citrus in creased following treatment with ethylene. Im proved color resulted primarily from an increase in the amount of an orange-red pigment, cryptoxanthin, and a red pigment, jg-citraurin. Tempera ture influenced pigment accumulation. At 65 °F and 75 °F, rapid accumulation of both cryptoxanthin and jg-citraurin resulted in highly colored fruit. At 85 °F,...

d'Anjou cv. pear fruit (Pyrus communis L.) exposed at harvest to 0, 0.42, 4.2, or 42 micromol m(-)(3) 1-methylcyclopropene (1-MCP) for 12 h at 20 degrees C were stored at 1 degrees C for up to 8 months. After storage, half of the fruit was continuously exposed to ethylene (0.45 or 4-18 mmol m(-)(3)) for 7 days at 20 degrees C. All fruit treated with 1-MCP had lower respiration and ethylene prod...

An optical chlorophyll sensing system was developed to detect the chlorophyll content of bananas as the fruit ripens. This system shows a high correlation to other peel colour analysis methods (spectral analysis, tristimulus colorimeter analysis, and visual colour matching). Regression equations were developed to predict the chlorophyll content of banana peels, which is primarily responsible fo...
